Title: [Factors affecting parameters of left ventricular diastolic function derived from Doppler echocardiography].
Abstract: According to the data from left ventricular catheterization as well as M-mode and two-dimensional echocardiography in 36 patients, the influence of left ventricular diameter, systolic function, systolic and diastolic filling pressures on the parameters of left ventricular diastolic function derived from Doppler echocardiography was analysed. The results indicate: (1) the left ventricular end diastolic pressure, rapid filling wave pressure and the ratio of the both significantly affect the Doppler diastolic function parameters; (2) the decrease of the ratio of early-to-late diastolic mitral flow velocities (E/A) is only a manifestation of early stage of left ventricular diastolic dysfunction and the E/A ratio returns to normal (false improving) at advanced stage of left ventricular diastolic dysfunction.
